Effects of physiological self-crowding of DNA on shape and biological properties of DNA molecules with various levels of supercoiling

DNA in bacterial chromosomes and bacterial plasmids is supercoiled. DNA supercoiling is essential for DNA replication and gene regulation. However, the density of supercoiling in vivo is circa twice smaller than in deproteinized DNA molecules isolated from bacteria. What are then the specific advant...
